Pivoting lever catch securable with a cylinder lock device

ABSTRACT

The present invention relates to a swivel lever lock which is securable by a cylinder lock device and is mountable in a thin wall, such as a sheet-metal cabinet door. The swivel lever lock includes a base plate having two projections penetrating through the door leaf. One of the projections serves for the connection of a rod drive or for an articulated shaft for a hand lever, which can be swiveled away. The projection can be used simultaneously for fastening one end of the base plate. The other projection has a recess for receiving the cylinder lock device holding the swivel lever in its swiveled-in position and can be used simultaneously for fastening the other end of the base plate. Either the base plate or the swivel lever has a recess for receiving a second cylinder lock which can be actuated independently of the first cylinder lock for securing the swivel lever in its swiveled-in position. The tappets of the two locking cylinders respectively act on a common locking element in such a way that the locking element can be released from the position in which the swivel lever is locked in its swiveled-in position by one of the two cylinder locks.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention is directed to a locking handle. More specifically, theinvention is directed to a swivel lever lock which is securable by meansof a cylinder lock device.

2. Description of the Related Art

A swivel lever lock having a single lock cylinder is known from the EP0261266A1 by the present Applicant. In this publication, there is acylinder lock arranged in the free end of the swivel lever.

DE 3407700A1 shows a similar construction in which, however, thecylinder which locks the swivel lever in its closed position is arrangednot in the swivel lever itself, but in the base plate. In contrast, theconstruction according to EP 0261266A1 has the advantage of a shorteroverall length, since a portion of the length of the swivel lever can beused to accommodate the cylinder securing the swivel lever. Adisadvantage consists in that the swivel lever is accordingly heavierand somewhat less convenient.

On the other hand, the device in DE 3407700A1 has an overall lengthwhich is greater, the swivel lever is somewhat more slender and has lessweight and can accordingly be operated somewhat more easily.

Each of the two known devices is provided with only one cylinder lock.

In certain applications, for example, switch cabinets which must bemonitored by both an electric utility company and customers of thiselectric utility company, it is advantageous or even necessary to lockthe lock with two different cylinder locks. A lock which can be operatedby two different cylinder keys is known from a catalog of the firmSteinbach & Vollmann. This lock can be a rod lock for two profilecylinders which can be locked by one or two cylinders in an optionalmanner. Similarly, this catalog also shows a bolt lock and the mortiselock No. 651/2 E748 which is also provided with an emergency unlockingdevice for high-voltage installations and can be mounted in steel doors.The lock can be locked optionally by one or two cylinders. One cylinderis provided for the owner of the switching installation and one cylinderis provided for the power supply utility company.

However, these locks, known from the Steinbach & Vollmann catalog, whichwork with two profile cylinders are not suitable for swivel leverapplications, since their construction is much too bulky. It is unknown,however, how to provide a swivel lever lock having two cylinders.

SUMMARY OF THE INVENTION

The object of the invention is to provide a swivel lever lock which isoutfitted with two cylinders, each cylinder allowing the lock to beunlocked and locked again independently of the other cylinder.

The object is met in that either the base plate or the swivel lever hasa recess for receiving a second cylinder lock which can be actuatedindependently of the first cylinder lock for securing the swivel leverin its closed position, and in that the tappets of the two cylinderlocks respectively engage in a common locking strip or tongue whichsecures the swivel lever in its closed position and can slide thislocking strip or tongue out of (or, if necessary, also into) itssecuring position against pretensioning force (e.g. spring force)independent from one another.

A very compact construction which can be conceived in differentembodiment forms is made possible in that the two tappets act on acommon locking strip (locking element). Thus, the locking strip ortongue or slide in order to lock the swivel lever could be placed behinda projection or edge formed by the base plate. Alternatively, the wallin which the lock is installed could naturally also serve as a contactsurface, but such an embodiment form is usually less favorable becauseof the careful machining of the openings in this wall which itnecessitates.

A particularly favorable embodiment form is characterized in that thetwo cylinders are carried one after the other, but particularly in analternative manner so as to be adjacent to one another, at the end ofthe swivel lever with reference to the longitudinal axis of the swivellever.

Alternatively, the two cylinders can also be arranged axially one afterthe other (with reference to the longitudinal axis of the base plate) oralso adjacent to one another in the base plate outside (particularlybelow) the trough arranged for the swivel lever stop.

More than two cylinders can also be provided when the cylinders arearranged axially one after the other with reference to the axis of theswivel lever or base plate. In this case, it is also possible to movethe locking strip or tongue out of the position in which the swivellever is locked in its closed position by means of correspondingfreewheel devices. However, an embodiment form in which a cylinder iscarried in the free end of the swivel lever and an additional cylinderis carried adjacent to the latter in the base plate has provenparticularly advantageous. One of the two cylinders can displace alocking strip into a first position in which the tappet of the othercylinder can lock in this locking strip and into a second position inwhich the tappet of the other cylinder does not achieve this position.

According to another embodiment form, the locking device is designed insuch a way that the locking strip or tongue is slid out of its lockingposition automatically when the swivel lever swivels into the base plateand the locking strip or tongue can slide back into its locking positionwhen the fully closed position is reached.

According to another embodiment form, the projection which is providedin the region of the locking devices can carry a cap attachment whichencloses the portion of the base plate and swivel lever reaching throughthe wall. With its edge, the cap attachment can contact the edgesurfaces of the opening in the thin wall provided for the projection andaccordingly clamp the wall between itself and the base plate, whichperforms a fastening function on the one hand and provides a seal on theother hand, particularly when the cap attachment forms a sealing lip atits edge or cooperates with a separate seal. The above-mentionedprojection can also have threaded bore holes for receiving fasteningscrews which fix the base plate at the thin wall, particularly in such away that they press a cap against the thin wall.

The openings can be round as in one of the examples of the prior art orrectangular as in the other example. In particular, the openings canhave the same width, but a different length. In particular, therectangular opening provided for the actuating shaft can have a lengthamounting to only a half or a third of the corresponding longitudinalextension of the other opening.

It has proven advisable that the length of the opening for the driveshaft be approximately twice as great as its width.

The swivel lever lock can be designed in such a way that it can bearranged in the fold space of a sheet-metal cabinet door, wherein oneprojection is part of a lock case in which flat rods of a rod lock aredriven and supported, and/or from which a sash lock proceeds.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1 through 3 illustrate a swivel lever lock 10 which is to bearranged in a thin wall 16, in this instance a door leaf, which ismounted on a switch cabinet housing 11. The swivel lever lock includes abase plate 18 and has two projections 32 and 34 penetrating the doorleaf 16 at rectangular openings 12, 14. These projections 32, 34 fix thebase plate in the openings 12, 14 so as to be centered. One projection32 serves for the connection of a rod drive 13 or at least forsupporting a drive shaft 15. A swivelable hand lever (also referred to,for the sake of brevity, as a swivel lever) being mounted at this shaft15 so as to be swivelable around axis 26, and extending verticallyrelative to the drive shaft axis 24. Two threaded pocket bore holes areprovided in the region of the projection 32 for screws 17 which can bescrewed into these pocket bore holes to press the box-shaped rod drive13 which receives the projection 32, against the contact surface 19 ofthe base plate 18. In turn, the door leaf 16 is clamped between thissurface 19 and the edge of the rod drive 13 enclosing the projection 32and accordingly affixing the swivel lever lock in the door leaf at itsupper end with reference to FIG. 1.

Alternatively (see the embodiment form of FIGS. 4 to 6, the opening 112provided for the drive shaft 15 can also be circular to receive abearing housing 21 for the shaft 15. The bearing housing can have acircumferential thread so that this bearing housing can be fastened inthe door leaf 16 by means of a union nut 23.

Referring to the embodiments of FIGS. 1 through 3, the box-shaped roddrive 13 serves for the displacement of flat ribbon rods 25, 35. In theembodiment form shown here, flat ribbon rod 25 extends to the lower endof the door leaf, ribbon rod 25 is guided in a rod guide 27 whichpositions the end of ribbon rod 25, behind a bevel 31 when locked. Theend of ribbon rod 25 may carry a stop wheel 29. The door leaf 16accordingly presses against the door frame edge of the switch cabinet 11at this lower end (possibly accompanied by the clamping of a seal strip33) and is locked. In a corresponding manner, an additional adjacent rod35 running in the opposite direction runs to the upper end of the doorleaf and causes the door to be locked in this location in an analogousmanner.

In the embodiment form according to FIGS. 4 to 6, the swivel lever lock110 shown in these figures likewise serves to actuate a rod lock of aswitch cabinet door. However, this lock has round rods 125, 135 whichare actuated in a manner known per se by a two-armed lever 37 which isfixed on the drive shaft 15. The ends of the round rods 125, 135 beingrotatably connected to the free ends of the lever 37 in a manner knownper se. Moreover, in this instance the shaft 15 carries a sash 39 whichconnects the door leaf approximately in the center of the cabinet withthe edge of the door frame or the switch cabinet housing so as to lock.The arrangement of these rods has been described in order to show thatthe arrangement of such rods is not impeded despite the portions of theswivel lever lock extending through the door leaf. Thus, in theembodiment form according to FIGS. 4 and 5, the distance between therods 125 and the inner surface 41 is large enough so that all parts ofthe swivel lever lock passing inward through the door leaf can beaccommodated in this area. In the flat ribbon rod lock according toFIGS. 1 to 3, a corresponding bend of the flat ribbon rod 79 likewiseprevents the part of the swivel lever lock penetrating the door leaffrom presenting a hindrance.

In particular, the lock, as shown in FIGS. 1 to 3, can also beaccommodated in the fold space of the door leaf of a switch cabinet.This space is a dead space which can normally not be utilized, but inthis instance provides an ideal accommodation for a rod lock. The narrowspatial conditions brought about by this nevertheless enable theembodiment forms shown in FIGS. 1 to 3.

Details of the swivel lever lock shown in FIGS. 1 to 3 will now bediscussed in the following.

The lower projection 34 of the base plate 18 forms a first insertionspace 76 for a cylinder lock 38 which is fastened in the base plate 18in a conventional manner by a fastening screw 45 extending transverselyrelative to this insertion space. In order to allow freedom of movementof the tappet 44 of the lock cylinder 38, the base plate is recessed inthe movement region of the tappet 44 and accordingly forms acorresponding annular space 47. Guide channel 49 and 51 access thisannular space 47, one channel on each side, and extends from thisannular space 47 past a material web 53 into a free space which is partof the receiving space 57 and reaches up to a projection 55 carried bythe end of the swivel handle. Projection 55 in turn forms a receivingspace 74 for receiving at least the sides of the cylinder 36 and enablesthe latter to be fixed in the projection 55 carried by the end of theswivel handle by means of a fastening screw 45.

As can be seen, the arrangement is axially symmetrical to a great extentand a slide or a locking strip 46 is arranged in guide channel 51. Aslide can also be optionally arranged in the guide channel 49 so as toslide along the channel axis. This strip 46 has a window-like opening 59with a width which makes it possible to receive the tappet 44. Thelength of the window 59 makes it possible to receive the tappet 44 alsoin the longitudinal direction and also enables an axial displacementwithin this guide channel under the action of this tappet with the leastpossible play. This slide or locking strip 46 reaches into the receivingspace 57 for the projection 55 carrying the cylinder 36 with its end 61remote of the window 59. The end 61 has a window-like opening or only anoffset 63 having a length such that the swiveling movement of the tappet42 of the cylinder 36 enabled under all other conditions is not impededin any position of the slide caused by a tappet 44.

As a result of this window or offset 63, a surface 65 is formed whichextends along the tappet movement and prevents the hand lever 22 fromswiveling out when the tappet 42 is located within this window or offsetspace 63. This is the case when the cylinder 38 has pushed the slide 46into the locking position at the top, which is effected in theembodiment form shown here in that the tappet 44 is rotated by 90° intothe position shown in the drawing from the position designated byreference number 67. That is, the slide or locking strip 46 is pushed upuntil the end 61 arrives in the region of the tappet 42 located in theshown position. On the other hand, when the tappet 44 is rotated backinto position 67, the locking strip 46 is moved downward until the end65 moves out of the region of the tappet 42 so that the latter is nolonger impeded by the strip 46.

This means that the swivel lever can be released by means of a cylinder38 when the cylinder 36 has its tappet 42 in the shown position.

Now the cylinder 36 can likewise be actuated by means of a key and thetappet 42 can be swiveled, e.g. particularly in such a way that it isswiveled downward by 45° (it then disappears in the cylinder) or rotatedin the clockwise direction by 90° so that it arrives in the region ofthe guide channel 49. However, no locking strip 46 according to thedrawing is arranged in this region. The swivel lever 22 can then beswiveled out in spite of the fact that the cylinder 38 is in the lockingposition.

Accordingly, exactly the desired function is achieved: the swivel lever22 can be released from the base plate 18 either when the cylinder 38 isbrought into the corresponding unlocking position 67 or in that thecylinder 36 is brought into a corresponding unlocking position. Anactuation of the other respective cylinder is not required.

The parts penetrating the door leaf 16 and the base plate 18 as well asthe swivel lever projection 55 are enclosed, according to the drawing,by a cover cap 40 which is supported by its edge surface 69 on the innersurface 41 of the door leaf 16 and in so doing encloses the projection34 of the base plate 18 on all sides. The cover cad 40 is fixed by meansof self-tapping screws (not shown) which are screwed into blind holes 71located in portions of the base plate 18, this being effected in such away that the door plate 16 is clamped in between the contact surface ofthe base plate on the one hand and the edge 69 of the cover cap on theother hand also at the lower end of the base plate (in a similar mannerto that effected at the upper end by means of screws 17) and the entirearrangement is accordingly fixed.

The cover cap 40 is kept narrow enough so that it can simultaneouslyform a lateral boundary of the two guide channels 49, but must have abulge 73 at least at one location so as to provide the tappet 44 withcomplete freedom of movement also in the direction of the wall of thecap 40. If a symmetrical arrangement is desired such bulges can beprovided at all four possible locations, but a single location isusually sufficient since the tappets 44 and 42 are adjusted and can beoperated by the key in such a way that such a bulge is not required forthe tappet 42 of the cylinder 36, e.g. this tappet moves at most aroundthe angle indicated by reference number 75 and the other tappet moves atmost around the angle designated by reference number 77 and requires thebulge 73.

Since a bulge 73 which enlarges the width is present only at one side ofthe cap 40, a relatively small bend 79 is sufficient for guiding theflat ribbon rod 25 past the cap 40, which flat ribbon rod 25 is guidedthrough the drive housing 13 to its drive and is therefore at adetermined distance from the axial line 81. A somewhat greater distancefrom the center line than is the case with the drive box is necessaryfor this. The rod can then be bent again behind the cap 40 into theaxial line 81.

If the type of door fastening is to be changed, e.g. from the right-handto the left-hand side, or the rotational direction of the drive for therods 25, 35 is to be changed, the arrangement known from EP 0261266A1can be used, in which case the rod 25 would reach to the other side ofthe cap 40. However, in this case, it would be possible by means ofmoving the slide 46 from the shown position in the channel 51 into theother channel 49 while changing the position of the tappets 44 and 42 ofthe cylinders 38, 36 in a corresponding manner. Now, however, anothercap is necessary which must have the bulge 73 for the tappet 44 on theleft side (as seen according to FIG. 3) instead of on the right side. Inorder to avoid having to stock two types of cap, a second bulge 173could be provided in an axially symmetrical manner at the right-handside of the housing 40 shown in FIG. 3 (in dashed lines). However, thissecond bulge 173 is not intended for the tappet 42, but for the tappet44 when the housing 40 is rotated by 180° so that the bulge 173 thenreaches the lower left-hand side of the arrangement. The entireright-hand side of the arrangement would then be free of bulges and therod 25 could be guided past more closely at the right side. (As can beseen, the bulge 173 is not suitable as a free space in the case of anaxially symmetrical construction with reference to the bulge 73, butnaturally could be extended far enough so that the tappet 42 could alsomove freely from the corresponding wall of the cap 40 if this should beadvisable for some reason).

If the operator possessing the key for the cylinder 36 wishes to actuatethe swivel handle lock, he can easily pull out the swivel lever by meansof the key inserted in the cylinder 36 after the tappet 42 has swiveledinto a position which no longer secures the swivel lever, even when theswivel lever 22 is enclosed in a type of trough formed by the base plateas shown. For the operator in possession of the key for the cylinder 38(that is, the cylinder arranged in the base plate), this possibilitydoes not exist and it can be relatively cumbersome to grasp the handlever 22 and swivel it out after unlocking the arrangement by means ofthe cylinder 38. For this reason, a spring 83 is provided in the regionof the axis 26 of the hand lever 22 at the actuating shaft 15. Thisspring 83 exerts a force on the hand lever directed in the openingdirection and allows the hand lever to be opened slightly automaticallyas soon as the lock is disengaged. This is particularly true in theevent that the unlocking is effected by means of the cylinder 38 so thatit is not necessary to pull out the hand lever 22 with the tips of thefingers in a cumbersome manner.

It is noted in addition that the receiving space 57 allows the swivellever 22 to be opened in every position defined by the angle 75 for thetappet 42, i.e. this space 57 continues up to the front surface of thebase plate. The gap 85 formed between the base plate 18 and the handlever projection 55 on the one side or area 87 on the other side isoutfitted with just enough play so that the opening is not impeded. Onthe other hand, no unnecessary wobbling movement results in the closedstate.

The size of the openings 12 and 14, respectively, necessary for theembodiment form shown in the drawing is selected in such a way that e.g.the opening 12 is the conventional opening also used in previous locksworking with flat ribbon rods. It has a longitudinal extension C equalto twice the transverse extension (B), i.e. B=2C. The opening 14 for thelock device having two cylinders likewise has a transverse extension B,while the longitudinal extension D=2C=4B.

These even-numbered ratios have advantages in technical respects relatedto manufacture.

The additional embodiment form as shown in FIGS. 4 to 6 carries twocylinder locks 136, 138 adjacent to one another, located in the free endof the swivel lever. These cylinder locks 136, 138 are inserted in turninto corresponding insertion openings 174, 170 and fastened by means oftransversely extending fastening screws 45, the cylinders beingextensively enclosed by material in this case. Partial annular spaces147 and 197, respectively, are provided and extend in such a way thatthe tappet 142 of the lock 138 or the tappet 144 of the lock 136 canmove out of the downwardly directed position into the position directedtoward the center by precisely 90°. Spaces 197 and 147 intersect at theswivel lever axis and are simultaneously penetrated at this location bya guide channel 149 in which a locking strip 146 can be displaced in areciprocating manner. As is the case in the embodiment form alreadyshown, the locking strip 146 has a window 159 in which, if the cylinderlock 138 is actuated, the tappet 142 engages or, if the cylinder lock136 is actuated, the tappet 144 engages during its respective swivelingmovement toward the center and in so doing displaces the slide 146upward from the locking position shown in the drawing. While in thelocking position, protuberance 160 of the slide 146 engages a stop face166 formed by the lever base plate 118. To effect unlocking, tappet 142or 144 enters window 159 to engage and slide strip 146 upward againstthe force of a pressure spring 156, into a release position in which theprotuberance 160 is released with respect to the stop face 166. As aresult, projection 155, and accordingly the hand lever 122, swivels outof the opening 89 formed by the base plate 118. A cover cap 140 is alsoprovided here. This cover cap 140 can be connected by means of fourfastening screws 249 with the base plate so that the door leaf plate 16is in turn clamped between the base plate and the edge of the cover cap140 and accordingly fixes the swivel lever lock at this lower end.

In the embodiment form shown here, the displacement strip 146 has aprojection 91 which serves to guide it, which projection 91 isdisplaceable so as to slide in a reciprocating manner in a correspondingguide groove in the hand lever 122, see reference number 93, and inaddition has a recess region 95 in which the pressure spring 156 can bereceived and guided on a screw 97 which can be screwed into a pocketbore hole (with self-tapped thread). This screw can likewise serve as aguide and can simultaneously serve as a stop for the outward movement ofthe slide 146.

The stop 160 formed by the slide 146 has a cam surface 219 which slidesalong on the outer edge 89 of the base plate 118 when the swivel leveris being closed. The lower edge of protuberance 160 slides along surface89, the spring 156 being compressed. Once face 166 is reached by thelower edge of the protuberance 160, the spring forces the protuberanceinto contact with face 166 to effect locking.

The swivel lever locks disclosed herein can be used commercially forexample in switch cabinet construction.
